RAS 180 Verse RO 150

I broke down after many years of waiting for the RAS 180 to come to the USA, it didn't,  so I just purchased it from Italy for 680.00 US, plus 85.00 shipping. I can't complain about that price. It seems to me if they ever did sell it in the US that would be on the very low end of the pricing for sure.

The RAS 180 is labeled with specs of 230/240 V 50/60HZ, 1500 watts, the cord plug rated at 230V 16 amp. This is perfect for the US. It's a double insulated tool. It works perfectly with the 220/240 in my shop using an EU Schuko to USA NEMA 6-20P plug adapter. I may just cut off the Schuko end and add a NEMA -6 plug end. I run the tool on a 20 amp circuit that measures about 236 V.


Comments:


Power: This is no joke the RAS 180 simply obliterated the Rotex in my short testing. The RAS 1500 watt rating appears to be real verse the Rotex 150's 720 watts.  I am so glad I ordered . The RAS 180 makes the Rotex 150 look like a toy, literally. I tested the sanders on some uneven Wenge work, the Rotex took me 5 minutes with 36 grit. The RAS 180 took me 85 seconds with 120 grit, I am sure once I know the sander that would go down to about 45 seconds. I was afraid to destroy the work so I stopped many times. I have not received the lower grit papers I ordered for the 180. Once I get the comparable papers I will video some real tests. I can't get the sander to stop even with my full body weight on it, there is just no way to stall the machine. I know, let the sander do the work, but if a job called for getting down pressure on the tool this can handle it.

Dust Control: The RAS 180 does not appear to be as good as the Rotex for dust collection, BUT I think this may be more a function of me getting use to moving the brush around as I sand as opposed to the machine. The RAS 180 of course doesn't have through the paper dust collection, it's like the RAS 115, just larger. After I get the proper papers and use this sander more  I'll update my assessment of the dust collection again.

If Festool does bring this beast to the USA I would love to see a redesign adding through the paper dust collection. Or maybe I really want a 180 size Rotex, but for now this 180 will be my go to for really tough sanding situations. Even with me not knowing the sander I caught 90% of the dust.

Build Quality: It's a Festool, everything is beefy and fits perfectly. It's made of plastic, but thank heavens it is. In all metal this might just be to just much to handle weight wise. As it is now no one is using this over their head.  The button used to hold the mahine in the on position just feels cheap to me. Time will tell if this is just my feeling or if it is really cheap. The power cord is EXTREMELY thin. Much thinner than on my Rotex. At 220V and 1500 watts the RAS 180 in the 220V version only pulls 6 to 7 amps, so though this thin cord is safe I would like to see a thicker cord(even if the wiring stayed the same within) simply because I am tough on cords in my shop. The 110V version(is there one?) would definitely not use this cord. This tool does NOT use a plug it end, it's a permanently fixed power cord.

Usability: This tool is a dream to use. It doesn't pull me around like a Rotex and is surprisingly well balanced. I thought I would be fighting it, trying to keep it from tipping and gauging work like many other sanders of this type, but the disc glides over the surface flat and parallel to the work. It's so smooth I have to constantly stop because I fear burning through the material.  There is no bite of the edge of the sander catching the material and this sander never hops or jumps around like on an RO sander tends to do.. For its size I don't see any tool of this type handling any better. I can even take my hand off the side handle and use the sander with one hand one the back handle, one hand on top of the disc area,  I have been using it like that often. There is no fear of the sander ripping out of my hands. Even at this great size and power the RAS 180 is easy to handle, it's much simpler to use  than any Rotex in rotary mode for sure.

I have only used this two days, once I master the tool Ill post a video.

Thanks for the review.  For those of us less educated on NAINA tools, is this just a larger/more powerful version of the RAS 115?

I've always felt like my RAS115 obliterates the 150, though I use them for very different tasks.  I've never felt particularly comfortable trying to use the RAS flat...use it more like a grinder...maybe I should give it a try.
 
Yep it's just the big brother of the 115, at least from my perspective it is.

I never felt my 115 was better or more powerful than my RO 150, therefore I sold it.  I do see your point and many have said that, but for my work the RAS 115 never felt more powerful than my RO 150. The RAS 115 wattage is less and that is how I perceived it as I used it for the few months I had one. The RO 150 for me just covers far more ground even if the RAS did seem to take a bit more material off faster for certain applications(stair treads being one).

With this RAS 180 it's not only twice as powerful as the RO 150 and three times more than the RAS 115, it's 180mm(near 7") pad make a huge differences for me, heck I would take an 8" in a heart beat. These wattage ratings arent just numbers this RAS 180 really acts twice as powerful as my RO 150, it's crazy.

The RAS180 is just a different animal as far as material removal, my days of sweating while I remove material are gone. Anything needing more power than this goes in the 50" drum sander, well if it's movable anyhow.

And I get your fear trying to use it flat,, it was of course my fear. But the 180 rides the surface flat as a pancake. Look a that star  under the sanders, I used the 180 to  flatten it. That star is only .325" thick so if I was to make a mistake it would become garbage, it worked perfectly. I even rode the 180 over the edge of the star tips and it didn't bust up those tips, it was a scary moment, but I had to know. Take a close look at the end of those star tips, they are very easy to break when they dont have surrounding wood and this sander floated right over them without gouging making them perfectly flat with the rest of the piece. Normally I wouldn't use this sander for this task, but it was a nice test to show this sander has some finesse!
 
I mean the proof is in the pudding on the star...definitely impressive.  I imagine it's the larger surface area of the 180 that gives confidence on flat work?  Would you have ever dared to do that with a 115?  I'll have to try my RAS flat sometime.

What type of paper did you use?  Always wondered why they don't make Granat for the 115 - just Rubin, Saphir, and Vlies.  I suppose it's because Granat was not deemed durable enough for typical RAS applications.  Did you get an idea of what papers they make available in Europe for the 180?
 
That looks nice...
You could out a neutrix connector on it, if you wanted a removable cord. If it is your only 220v then it might not make sense unless you you have it attached to a hose.
 
In OZ the RAS180 goes for $1,375.

I've haven't had the urge to acquire one ... until now [member=3373]Dovetail65[/member] $@%#%%@!!!!! [mad] [embarassed]

Rotary sanders (like rotary polishers) are tools that have the ability to perform tasks extremely quickly, but can be very unforgiving if you don't know what you're doing (let a novice loose on a car with a rotary polisher and the top coat will be cut to pieces with ugly swirls).

The RAS180 does fit into the "beast tool" category ... it seems you can even get a stirring rod adaptor for it [eek]

Here's the Festool Oz link for anyone interestedhttp://www.festool.com.au/epages/to...ooltechnic/Products/570743/SubProducts/570743
 
Nice to see something about the RAS 180, it is extremely rare to see an owner here on the FOG.

No surprise it totally blows the Rotex out of the water, it's in an entirely different category. Even the small RAS 115 is quite a bit faster than the Rotex at removal. The higher RPM has a lot more to do with it than wattage. The 180 ofcourse having higher RPM, disc size and wattage makes all the difference.

Having a RO150 and RAS115 the RAS180 is something I lust after but do not need at all. We had a 230mm rotary sander at my father's body shop, it only came out if we had to spray an old truck or metal siding of a building.
 
Very cool! I would love it if they offered these in North America. I use my RAS 115 all the time and a bigger version would be great to add to the arsenal. More pics and comments when you get a chance, please. It is good stuff.
